WIBE-STRETCHER.

To all whom it may concern Be it known that I, PETER FILLmZ, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented new and useful In'iprovements in lVire-Stretchers, of which the following is a specification.

This invention relates to wire stretcher-s suitable for use in laying telegraph lines where an especially light but powerful. device is required on account of the fact that the implements have to be ported often for considerable distances, and considerable force is necessary to maintain the wires at proper tension while being secured.

It is an important object of the invention to provide a novel and eflicient form of gripping means adaptable to various sizes of wire. A further very important object is to make it possible to engage the stretcher with the cross arm of a telephone pole to stretch and hold a wire while it is secured to the usual insulator upon the arm, without interference with the work.

It is also an important aim to enable the use of the device on each side of a pole with equal facility, and allowing it to be operated always on whichever side is toward the pole, to which the lineman usually clings while performing the work. Thus the workman does not have to assume more dangerous positions for the operation of the stretcher than are necessary for the performance of his regular work in securing the wires in place.

It is another object to arrange for the secure retention of a wire in proper position in the gripping devices after adjustment, for, owing to the awkward positions the lineman is often forced to assume when at the head of a pole, it is often impossible to handle the device in such a way as to allow the wire to feed straight thereto.

Other details of this invention are covered by my application filed March 26th, 1912, Serial Number 686,296.

A further object is to make it possible to operate the device entirely with one hand, and other objects and advantages may be apparent from the following specification and the drawings, in which- Figure 1 is a top view of the device engaged with a cross arm, Fig. 2, is a side view thereof.

There is illustrated a stretcher comprising Specification of Letters Patent.

the shank 10 having the enlarged boss 11 adjacent one end, with the reduced slightly conical pivot bearing 12 outwardly of the boss and concentric therewith, a threaded stem 18 extending up from the bearing. Projecting longitudinally from this end of the shank there is a reduced stem 14, upon which there are swivelcd the two anchor hooks 15 and 16, the latter being the enter one, and each being independently movable. A lever 17 is centrally pivoted on the bearing 12, being held by means of a nut engaged with the stem 13. Each end of the lever is socketed as at 19, to receive detachably an operating handle 20, as shown.

It will be seen that the lever 17 is spaced from the adjacent surface of the shank 10, so that a link 21 connected pivotally to the lever on its inner side may reciprocate freely upon the adjacent side of the shank. This link projects longitudinally beyond the end of the shank farthest from the lever, and carries a grip device to be subsequently described. The said end of the shank is broadened and provided with standards 22 across which a retaining cross piece 22' is secured, whereby the link is held slidably upon the shank. A second link 23, shorter than the one 21 is connected to the lever on its outer side, and also on the opposite side of the lever pivot from the connection of the first link. This second link is held slidably in superposition on the first link by means of standards 24 and cross piece 24/ similar to those 22 and 22, and arranged in similar relation to the shank intermediatcly of its length.

An important feature to be noted here is the fact that the standards are spaced transversely a greater distance than the breadth of the links, so that the latter have a consid erable amount of play transversely of the shank in one direction, while the cross pieces 22 and 24' hold them securely against transverse movement to and from the shank. The allowance of this play overcomes or obviates a large amount of friction in the engagement of the device with wire in operation, as will be subsequently explained.

Each of the links is provided at its free extremity with a grip device 25. The link 23 has an extension 26 projecting laterally therefrom in the plane of the link and serrated at 27 on its upper side forming ribs and grooves parallel to the link. This eX tension is divided in two by a slot 28 transverse to thelink and Opening on theup'per: and lower faces of the extension and on its Spaced inwardly from the slotouter edge. on the upper side of the link there is a pivot pin 29 pivoted upon which there is a cam dog 30 arranged to bear against the rough-j ened adjacent face 31 of an adjustable block 32 serrated on its under side to fit snugly! upon the extension 26, and havinga bolt--33 pivot so that a wire tending .to pass outwardly between the dog and block willibe engaged bindingly and wedged therebetween. The dog. is provided with an arm 35, extending laterally from the shank and having a headed pin 36 on its uppersideadjacent itsext-remity borne upon by the arm 37 of a wire spring having a helix 38 set upon a suitablepin carried bytheblock 32theop- .peei nd re wvire being ex nded to term an arm39 engaged against a lug 40 on the block whereby the arm 37 is caused to exert force upen .the dog to cause it to engage properly .upo-n wire in the device.
